ARK Buys $16 Million of CoreWeave, Trims Palantir by $10 Million

ARK Invest bought 283,022 CoreWeave (NASDAQ: CRWV) shares on Thursday, November 12, 2026, a purchase worth roughly $16 million, executed on a day the stock fell 6.86% to $56.60. The same funds sold 58,339 Palantir (NASDAQ: PLTR) shares worth about $10 million. Palantir barely noticed, dropping 0.48% to $171.58.

ARK has not explained the trades. The pattern, however, is plain: Cathie Wood's firm added to a debt-funded AI infrastructure builder after a decline, and reduced an AI software winner that trades at a premium price. One bet on leverage, one trim on valuation.

What exactly changed in ARK's portfolio?

Both trades ran through the flagship ARK Innovation ETF (BATS: ARKK) and a sister internet fund. The November 12 holdings file for ARKK shows roughly 2,431,528 CoreWeave shares, equal to 2.37% of the fund, alongside about 948,590 Palantir shares, or 2.63%.

The Palantir sale was one piece of a wider rotation rather than a verdict on the company. On the same day ARK bought about $8.9 million of Twist Bioscience (NASDAQ: TWST) and sold slices of several other holdings. Palantir remains among ARKK's larger positions, so the sale reads as a trim, not an exit.

The CoreWeave position, at 2.37% of ARKK, is small enough that a high-risk fund can absorb the loss if the thesis fails. That sizing is the quiet part of the strategy.

Why did CoreWeave fall in the first place?

The dip followed a genuine surge. CoreWeave reported third-quarter results on November 10 and closed that day at $48.73. On November 11 the stock rose 24.71% to $60.77. On November 12 it fell as low as $50.17 before closing at $56.60 — still above the pre-earnings level, but down 27.26% for the month through that date.

Two causes were reported for the slide:

• Soft guidance from a rival, the AI-focused cloud provider Neocloud
• Doubt about support from NVIDIA (NASDAQ: NVDA) after Jensen Huang resigned as its CEO

NVIDIA invested $2 billion in CoreWeave stock in January 2026. CoreWeave's chief executive said he saw "no reason" for the partnership to change — but he said it on November 11, before Huang departed. Timing, in this business, is everything.

How do the two businesses compare?

CoreWeave carries a market value of about $25.97 billion. Its third-quarter revenue grew 168% to $3.66 billion, and its backlog stands at $132.5 billion — nearly its own market cap times five. Against that, the company plans $37 billion to $39 billion of capital spending and lost $709 million in the quarter, including $846 million of net interest expense.

The backlog locks in future revenue. It does nothing for the cost of financing that spending, nor for customer concentration: the top customer generated about 67% of 2025 revenue.

Palantir presents the opposite profile. It is valued at about $395.78 billion, with a debt-to-equity ratio of 0.03, a net margin of 36.3%, and third-quarter revenue up 95.9% to $2.313 billion. The cost of that quality is a price of roughly 244 times earnings.

What are analysts saying now?

On November 12, Barclays cut its CoreWeave price target to $85 from $105, and Argus cut its target to $100 from $150. Both figures remain well above the share price. Even so, the reductions arrived immediately after a quarter that beat estimates, which suggests analysts now price in more financing risk.

What should investors watch next?

CoreWeave carries heavy debt and an at-the-market equity program of up to 35 million shares — new stock sold gradually into the market, diluting existing holders. Its key supplier, meanwhile, has new leadership at the top. For investors near retirement, the source flags this as significant risk.

Palantir's own drawdown has done some of the valuation work. Its 17.77% drop through November 12 has cut the price investors pay for growth that remains intact, and the company expects $4.8 billion to $5.0 billion of adjusted free cash flow for 2026.

The next marker is NVIDIA's earnings report on November 17. If CoreWeave closes below $48.73 after that report, it will have surrendered its entire post-earnings rally — a signal of deeper financing concern. A close back above $60.77 would suggest the November 12 drop was merely noise.
